Hello.
There are some questions about EXT_LFx pin of ADV7344.
The datasheet says that 12nF, 150nF capacitor and 170ohm resistor should be connected to EXT_LFx pin.
The issue occurs that mechanical shock by external makes some abnormal picture.
So, they tried to reduce the capacitor value(12nF->1.2nF, 150nF->15nF), then the issue is fixed.
Can ADV7344 accept above reduced capacitor value?
Best regards.
Kikka
